| 摘 要： | 运用线性波浪理论和刚体运动学原理,建立了波浪作用下网箱浮架系统的计算模型.在不同波高(H=4.2～7.0 m)和周期(T=7.2、8.6 s)条件下,采用计算机数值模拟方法,分别对浮架系统所受的锚绳力、波浪力以及合力矩进行了数值计算.通过计算结果的比较及分析表明,三者都随波高的增大而有所增大,其中迎浪侧锚绳力和水平波浪力与波高都有显著的正比关系.在各种不同波况下,迎浪侧锚绳力要大于背浪侧锚绳力,水平波浪力要大于垂直波浪力.

| Abstract: | A numerical model for floating collar exposed to waves was set up by using the linear wave theory and the rigid body kinematics principle. In this paper,under the conditions of different wave heights(H=4.2~7.0 m)and wave periods(T=7.2,8.6 s),employing computer numerical simulation method,the forces on the mooring lines of the floating collar,the wave forces and the driving moments for the collar were calculated respectively. By comparing and analyzing,the calculated results showed that with wave height incr... |
